electromagnetic waves

"This book is about [the history of] x-rays [and how they are used]"--Provided by publisher.

Microwaves heat our food. They carry messages from phone to phone, and they help detect the weather. Microwaves are all around us, even if we don't see them. Readers will learn about microwaves and how we use them every day.

Radio waves aren't just for listening to your favorite radio station. They are used to make GPS receivers and wireless internet work, plus scientists use radio telescopes to help them study space. Readers learn about radio waves and how we use them every day.

Introduces young readers to the basics of light, discussing what it is and how it works.

Introduces electromagnetic and mechanical waves, discussing the properties of waves, the electromagnetic spectrum, and vibrations.

Introduces readers to waves, illustrating how waves are a transfer of energy, not of matter.

Explores how light and sound waves transfer information.

The first time the term ?tractor beam? was used was in 1931. Since then, tractor beams have been used in many science fiction books, movies, and TV shows to draw in spacecraft, people, and objects in space. This science fiction technology has become science fact. In 2015, scientists used sound waves to move tiny objects. Through reading about this and other modern technology, readers are engaged with incredible STEM information as well as their imaginations as they also learn the connections between this technology and popular science fiction.

"This engaging book describes the properties of light waves, how they move, and the way our eyes receive them. Readers will learn that we see an object when light reflects from its surface and into the eye. A link to interactive activities online plus an activity in the book allow readers to create models that explore how to redirect and block the path a light wave travels."--.

"This ... title introduces readers to the concept of a wave and the patterns and properties common to both light and sound waves. Clear text and detailed diagrams combine to demonstrate the cause-and-effect relationships involved in the properties of amplitude, wavelength, and frequency. A link to interactive activities online plus an activity in the book allow readers to explore key concepts close up by creating their own wave models."--.
